Model for Cyclic Fatigue of Quasi-Plastic Ceramics in Contact with Spheres

Abstract

A model of contact damage accumulation from cyclic loading with spheres and ensuing strength degradation in relatively tough, heterogeneous ceramics is developed. The damage takes the form of a quasi-plastic zone beneath the contact, consisting of an array of closed frictional shear faults with attendant “wing” microcracks at their ends. Contact fatigue… (More)
